Abstract:
PROBLEM TO BE SOLVED: To provide a method of adjusting a particle size in a polysilicon layer, and to provide a device manufactured by the method. SOLUTION: In the method, the polysilicon layer is formed on a substrate and the particle size in the polysilicon layer is adjusted so that the average resulting particle size of the polysilicon layer after a polysilicon particle-size adjusting ion is injected into the layer and prescribed annealing is performed on the layer becomes higher or lower than an average resulting particle-size that must be obtained after the same annealing is performed on the polysilicon layer without injecting the ion into the layer by injecting the particle-size adjusting ion into the polysilicon layer.

Abstract:
A programmable device includes a substrate (10); an insulator (13) on the substrate; an elongated semiconductor material (12) on the insulator, the elongated semiconductor material having first and second ends, and an upper surface S; the first end (12a) is substantially wider than the second end (12b), and a metallic material is disposed on the upper surface; the metallic material being physically migratable along the upper surface responsive to an electrical current I flowable through the semiconductor material and the metallic material.
